Picked up an MS 440 today off Craigslist. The guy wanted $500 OBO, but he had misstated the bar length so I beat him up a little and got it for $400. He has had it for 3 years and said he doesn't use it very much and it is a lot of saw. I took the muffler cover off and piston and cylinder wall look pristine. The chain was in a sad state so I spent a lot of time sharpening it and the noodled the stump of an oak that fell in my yard with it. The saw has a 20" bar on it, the previous owner had said it had a 24" bar. Honestly I was fine with a 20" bar because it will just fit in the work box on my truck, but I would like to also buy a longer bar and chain combo for the saw. Is a 28" bar a too much for the saw? I see I can buy a dual port muffler for this saw. I did a MM on my MS 390 and that woke it up. What can you expect from dual porting a 440?
